To think DS2 knows when I try to have an early night and decides to wake up.

[fruitstick]

He's 2.5. Really good sleeper and never wakes up - except if I'm really tired an tried to have early night (well I was in bed by 11).

He's gone back to sleep but DH Is away and now I can't go back to sleep. Keep thinking I hear noises which is almost certainly the central heating but is making me anxious.

So now I'm going to be even more shattered than normal [angry{

Yes, DCs always Know.

They also Know when you are on a tight schedule and need to be out of the house within 5 minutes. Perfect time for a dirty nappy/toilet visit/tantrum/feed.

Especially if you're going on holiday and trying to pack.
